There are basically two ways to deal with terrorists, talking and acting. In 1986 some radical Islamic group kidnapped four Russian diplomats and killed one of them to demonstrate seriousness. The Russians then grabbed a family member of the terrorists, murdered him, and sent his body parts to the terrorists, who promptly released the remaining 3 diplomats.
Now, I'm not saying we murder family members of the ISIS savages in retaliation for beheading a US journalist, but the point is, the Russians acted while our effete President talked, offering a pro forma statement that accomplished nothing, then skedaddled back to the golf course.
ISIS bodies should be piling up by the hundreds if not thousands by now, but the mincing community organizer who we are asked to regard as President hasn't got time for anything but vacation golf and having his ass kissed by the media.
